The purposes of this study were to find out the ability of students in Skimming and Scanning and to investigate how the students apply the procedure in Skimming and Scanning in Reading class. This study applied a descriptive qualitative approach. The writer used purposive sampling. The writer had nine respondents. The writer used documentation and observation as the instrument. Based on the results, indicated that in skimming, the students made a question, some also looked at the table of contents, they read or browsed at high speed, but some students were still affected to Look at reading topics. Then all students stopped when they found the topic they were looking for. but some students were not careful when text a reading. In scanning, the students also saw the table of contents first, but some students directly browsed to the page they wanted to find, besides, the students also read the background, and they also read the conclusions at a glance.

This research is motivated by the low activity and learning outcomes of students in one of the public high schools in Bima City. The purpose of this research is to increase students' activities and learning outcomes of mathematics by applying Personalized System of Instruction (PSI) learning. The type of research used in this study is quasi-experimental, it is said that because in this design the researcher cannot control all external variables, namely external factors that are not examined and become a nuisance so that it affects the course of the experiment. The results of this study indicate that all aspects that are assessed appear during the learning process. This is complemented by the results of statistical tests with the results of tcount greater than ttable, namely 2.86 > 1.67 with the acquisition of the average value of learning outcomes in the experimental class which is greater than the control class, which is 65.8 > 53.9. This means that the Personalized System of Instruction (PSI) learning model gives better results than conventional learning. Thus, the steps of the PSI learning model have an influence in increasing students' activities and learning outcomes in mathematics.

Penelitian ini dilatarbelakangi oleh masih rendahnya kreativitas dan hasil belajar matematika siswa  SMP 13 Negeri di Kota Bima. Adapun tujuan dari penelitian ini untuk membuktikan pengaruhn Model Pembelajaran Group to Group Exchange terhadap kreatifitas dan hasil belajar matematika siswa. Jenis penelitian yang digunakan dalam penelitian ini adalah quasi eksperimen, dikatakan begitu karena dalam desain ini peneliti tidak dapat mengontrol semua variabel luar yaitu faktor luar yang tidak diteliti dan menjadi pengganggu sehingga mempengaruhi jalannya eksperimen. Adapun hasil penelitian ini menunjukkan bahwa semua aspek yang dinilai muncul pada saat proses pembelajaran berlangsung. Hal tersebut dilengkapi dengan hasil uji statistik dengan hasil thitung lebih besar dari ttabel yaitu 2,46 > 1,98 dengan perolehan nilai rata-rata hasil belajar kelas eksperimen lebih besar dari kelas kontrol yaitu 95 > 75. Hal ini berarti bahwa model pembelajaran Group to Group Exchange memberikan hasil yang lebih baik dibandingkan dengan pembelajaran konvensional. Dengan demikian bahwa langkah-langkah model pembelajaran model pembelajaran Group to Group Exchange memberikan pengaruh dalam meningkatkan kreativitas dan hasil belajar matematika siswa.
